Patented Dec. 15, 1914.

Application filed March 11, 1913. Serial No. 753,583.

To all whom it may concern Be it known that I, EDWIN Moonn, a subject ofthe King of England, residing at Audrey, in the Province ofSaskatchewan, Canada, have invented certain new and useful Improvementsvin Automatlc Shockers;

and I'do hereby declare the following tobe' a' full, clear, and exactdescription of the invention,'such as will enable others skilled to makein the art to which it appertains and use the same.

This invention relates to automatlc shock formers, and more particularlyto thattype of shock'former which is norma1ly'hor1zon-. tal and movableto a vertical posltion by means of mechanism carried by theshock formerframe, and an object of the nvention is to provide improved means forraising and lowering the shock former from a horizontal to a verticalposition and back.

Another object of the invention is to provide a tilting shock former Ywith agate. which serves to pass the bound sheaves,

from the binder to the shock former receptacle. I

Another object of the invention is to provide tines so controlled by theswinging action of the shock receptacle that the t nes will bepositively driven to follow the sheaves to the ground and force the samein,

the stubble.

Anotherobject ofthe invention is topro: vide a bottom for-a shock formerflexibly connected with the tines so that as the receptacle falls to itsnormal horizontal position, the tines will return the bottom to normalposition. l

A still further object. of the invention is to provide means forpreventing the misplacement of sheaves when the shock former is not inposition'to receive the sheaves, and to further provide means actuatedby the door as the latter opens to permit the sheaves to be passed intothe receptacle.

A still further object of the invention is to provide an adjustable tripfor the purpose of stopping the rising action of the shock former at anypredetermined position, and in further providing resilient means forstarting the shock former on its return motion.

A still further object of the inventlon is to provide adjustable meanscarried by ,a

frame on the shock former for. automatically releasing the bottom oftheformer normal horizontal position and when the latter has reached apredetermined position. a

A still further object of the invention is to provide a gate for a shockformer which may be partly closed when the operator so desires, for thepurpose of packing the sheaves within the former, the means foraccomplishing this also making it necessary that the gate or door becompletely closed before the shock former starts to rise.

With these and other objects in view, the invention consists in certainconstructions, combinations and arrangements of the parts which will behereinafter more fully described, and thenspecifically pointed out inthe claims.

In the drawings, Figure 1 is a side elevation looking from the binderwith the shock former in position to receive sheaves; Fig. 2 is a sideelevation from the opposite side of the shock former showing the same inelevated position just before the bottom is re leased; Fig. .2 is aperspective view of the bottom of the former,.showing the manner ofpivotally mounting the same; Fig. 3 is a front elevation of the shockformer showing the relation of the parts just after the bottom has beenreleased; Fig. 4: is a perspective view of the trip and trigger used forlocking and unlocking the bottom of the shocker; Fig. 5 is a detail viewof a modified means for returning the tines; Fig. 6 is a perspectiveview showing a portion of the conic former, and pawl and ratchet forcontrolling the passage of the sheaves in the former; and Figs; 7, 8 and9 show diagrammatically the action ofthe cam rods The description of themachine disclosed herein will be given at successive stagesof theoperation thereof, beginning with the throughout a complete operation.

Referring to the drawings, the frame 1 of the shock former is shown asconnected to parts of a binder 2, this binder being ofany approveddesign and provided with the usual delivery board 3, the binder with thedelivery board forming no part of the present' invention. By means ofthe brace 4,

proceedin secured to the upper end of the frame 1, 1

the entire'frame is secured to the binder for the purpose ofstrengthening the same, the

frame 1, is a shaft 6 having thereon a' ratchet wheel 7 provided with aplurality 1 of teeth 8. Arms 8 are located just below the mouth of thedelivery boar-d3, and are adapted to prevent the transference of sheavesfrom the delivery board 3 to the shock former vwhen the latter is not inposition to receive them. Pivotally mounted on the standard 5, is a pawl9 having extending therefrom a tooth 10 adapted to en gage a slot 11formed in the ratchet wheel 7, the slot 11 having its sidessubstantially perpendicular to the periphery of the wheel 7 so that thesaid wheel 7 cannot be rotated in either direction when the tooth 10 isin the slot. The pawl 9 has extending beneath the ratchet wheel 7, anarm12, the

purpose of which will be described hereinafter.

The" container for the. shock former is composed of an'upper ring 13 anda comparatively larger lower ring 1 1, between which extend suitablebraces to which is secured a sheet of metal 15 formed substantially inthe shape of a truncated cone and adapted to receive the sheaves andform the same in a shock previous to the delivery of said sheaves.Pivotally mounted in the upper and lower rings, is a door or gate 16,which gate 16 is designed to rest upon a side bar 17 forming part of theframe of the shock former, or this side. bar 17, may

be part of the binder. When the gate 16 is in the position shown in Fig.1, it is designed to be placed beneath the arm 8, the gate in thisposition being adapted to pass the sheaves from the delivery board 3 tothe shock former 15. Extending from one end of the gate 16, is a triprod 18, which is adapted to engage the extending end 12 of the pawl 9just as the shock former is being lowered from theraised position, thisen- 1 gagement of the extending end 12 by the trip rod 18, beingsuiiicient to raise the tooth 10 from theslot 11, so that the arms 8 maybe rotated by'reason of the weight of the sheaves accumulated thereon,and thereby pass saidsheaves over the gate 16 into the shock former. Byreferring'to the ratchet wheel7, it will be noted'that the teeth thereonare so related to the tooth 10, as to permit the arms 8 to be rotated inone direction only, this direction being in the path p, of themovingsheaves.

After the requisite number. of sheaves have been placed within the shockformer, the same is elevatedto'the position shown substantially in Fig.2, by means of the mechanism carried by. the frame comprising a tractionwheel 19- journaled within the frame 1 and-having a shaft 20 upon whichis slidably mounted a. drum 21 and 'a clutch member 22,-this clutchmember; being I actuated by a lever 23' pivoted as 'a't'24t in the sidebar 25 of the frame 1. Pivotally the drum will Wind up flexible chain,-cord 7 or other connection 27, this chain 27 being trained over a pulley28 provided with suitable guards to prevent the slipping of the chainand also over a second pulley 29 de-' pending from a cross bar 30connecting the side bars; 5 and From the pulley 29, the

chain 27 passes around a pulley 31 swiveled lVhen the lever 23 has movedtheupon the upper ring 13 of the shock former, p and connects to theupperouter end of the gate Therefore, it will be seen that when the'drumis drawn into engagement with the traction wheel by means of the clutch,theflexible connection will draw upon the gate '16, and move the same ina direction 'to close the shock former 15. Mounted uponthe upper ring 13and connected tothe outer upper end of the gate 16,

is-a spring 32 which opposes the closing of the gate, serves to hold theflexible member 27'taut, and also serves to open the gate 16 wheneverthe flexible member 27 is released, or becomes slack. After the gate 16has'been drawn tightly closed against the metal sheet former .15, andthe drum continues to rotate,'the chain 27 will begin to move the shockformerto a vertical position, the lower ring 1 1 being provided withtrunnions 33 and 34.- journaled In side bars 25 and 5 respectively, toadmit of this rotation.

*As the shock former beg ns to move to its,

vertical position, a tine rod 35 will be constrained to move downwardlyand to engage thetops of the sheaves. TlUS t'lllGl'OCl 35 is slidablymounted within a bracket 36 and has an adjustable stop 37mou'nted'thereon for the purpose of limiting the downward movement thereof.Formed" at the lower end of the tine rod 35, is a plurality of tines 38which may be of any suitable number and size, and connected to the tinema in any f suitable way. Interposed between the'tin'es 38 and thebracket 36, and loosely surrounding the tine rod 35, is a spring 39,this spring being a long compression" spring so 1 designed as to expandsufliciently to force the tines downwardly with the sheaves as thelatter-'dropto the ground from the shock former. Within the spring 39,and rigidly spring 39 reaches its maximum compresthe load of thelifting-strain from the spring and transfer it to the bracket 36. I

. Rigidly connected to the upper. outer end of the gate 16, is a benttrip rod 41, this trip rod 41 .being adapted to engage a similar 00-operating trip rod 42 rigidly secured to the" outer end of the shaft 6.These bent trip rods are so related to each other that when the gate 16is pulled upwardly by the flexible chain 27, the rod 41 a will act uponthe rod 42 to send the shaft. 6 around to a position where the arms 8will again be in the path of the moving sheaves. It will be understoodthat as the gate 16 assumes the position shown in Fig. 1, the trip rod18 will act upon the extending end .12 of the pawl 9 and thus releasethe ratchet wheel 7, the ratchet wheel 7 remaining unlocked until thesame has been rotated sufliciently by the turning of the bent rod 42 bythe bent rod 41 for the slot 11 to move again under the tooth 10. Afterthe tooth 10 has been removed from the slot to permit the accumulatedsheaves held back by arms 8" to pass upon the gate 16, the ratchet wheelwill be free to rotate in theidirection oftravel of the sheaves(clockwise looking at Fig. 3),

and is prevented from returning by the teeth engaging the tooth 10. Thearms 8, and hence wheel 7, turn because of the pressure of theaccumulated sheaves when the pawl 12 is tripped, and the force of thedescending sheaves is found sufficient tothrow over the'shaft and arms8. After being thrown over the arms 8 will fall to the position shown inFig. 3 by gravity. Under normal conditions the sheaves passing over thegate 16, will force the arms 8 and the bent rod 42 around to such aposition that the. said rod 42 will be engaged by the bent rod 41 as thegate is raised by the flexible chain 27 To insure that arms 8' willreturn as just stated and to avoid annoyance should the sheaves notforce the arms 8 through a complete revolutionarods' 41 and 42 areemployed. In order; better to understand the action of rod 41 upon rod42, reference is to be had to Figs. 7, .8 and 9, where a series ofviews. isshownillustrating successively the positions the rods assumewhen acting to return shaft 6 tonormal position. It will be assumed thatthe sheaves have just passed the arms into the former and that,therefore, tooth 10 is'out .of slot 11 formed in wheel 7: In thisposition .the

' arms 8" will be depending below shaft -6 and rod 42 will besubstantially at the bottom of shaft 6. As the flexible connection 27 isdrawn, taut after the sheaves have passed into the former to closefthedoor 16,. the rod 41 carried by the door will rise and turn toward shaft6 in a direction which is counterclockwise when looking from the lefthand side 'of Fig. '7. The rod42-is provided with" a curve. y betweenstraight "portions a and b, which curve 3 is engaged by the curve as ofrod 41. Inasmuch as portion '6 of rod 42 extends downwardly and awayfrom the reader, it will be understood that as rod 41 continues torotate I toward shaft 6, the curve a: will slide along of their ownweight. In order to give the slightfurther motion to shaft 6, which willshift the center-of gravity of the arms 8 across the axis of shaft 6,the straightened portions 2 extending from curve an of rod 41 willengage the portion v,0 of rod 42 as rod41 continues to rotate due to theclosing of the door 16. Portion 0 extends downwardly and away from thereader as viewed ,in Fig. 8, so that as portion 2 slides along part 0the shaft 6 will be given. a further slight rotation, which will besufficient to shift the center of gravity of the arms 8 from the rear ofshaft 6 to the front thereof, after which the shaft will rotate-andarms. 8 fall to their normal position. It is to be understood, ofcourse,that ratchet wheel 7 prevents retrograde movement of shaft 6before the arms 8 pass over the I shaft 6, but that said ratchet wheelenables the arms to fall to normal position uninterruptedly. Fig. 9shows the relation of the two rodsjust at the point when the center ofgravity of the arms is shifted from one side of shaft-'6 to the other.

When the shock former has assumed the position shown in Fig. 2, thesheaves are ready to be unloaded, and the whole weight of the sheavescomes upon the bottom 43 which is pivotally connected to guide rods-44,w hich pass through a brace45 rigidly connected to the shock former15. These guide rods 44 are provided with suitable adjustable stops 46for limiting their downe ward movement, these stops being adapted toengage the support 45. Pivoted to the.

ring 14 on the under side thereof, are levers 4747 each actuated: by asuitable spring 48, which normallyholds one end of the correspondinglever ,under the prongs 49 of the bottom. a 1 Adapted to engage theouter end ofthe lever 47, is a trigger 50, which trigger isadjustablymounted upon the side bar .5, so that the same may be moved ineither a .vertioal'direction, or move aboutits pivot 51, as a center,thetrigger being provided in its, lower end with a slot permittingof a isuch as a" spring 56 securedto theside bar-5 and engaging the brace i5.

shock former on its return. p Y

, When the shock former startson its re-' and-is securedto one side ofthe'pivotpoint 9 vertical movement around the pivot nut 52. This trigger50 may be adjusted so'as to en'- gage the outer end of the lever 47 atany predetermined position of the shock former. Wherethe sheaves arelong and the shock formed thereby is comparatively tall, it will bedesirable to allow the shock'former to pass slightly beyond the verticalposition so that the rear end of the ring l lwill not engage the tops ofthe sheaves forming the shock to'upsetthe same, whereas it-is obviousthat if the sheaves be short, the same may be delivered assoon as theshock former assumes a vertical position. When vthe lever i7 is trippedby the trigger 50, the bottom 43 will be free to descend and will fallcompletely to the ground and carry the formed shock therewith. Inasmuchas the shock former is moving continuously "in the direction of thearrowas shown in Fig. 2, and inasmuch as the protruding stubbleof the grainwill catch the lower ends of the sheaves, the shockwill be held on theground at the place whereit falls and the bottom will move outwardlyfrom thereunder with the shock former. At the moment of delivery, it isdesirable 'to have the drum 21 disconnected from the traction'wheel, andthis is accomplished by means 075 a trip 53 adjustably mounted upon atrip rod 54, whichtrip rod 54: has an extending end 55 whichis pivotallyconnected tothe lever 23. The trip 58 is designed tobe in the; path ofthe brace 45, which brace a5 is adaptedto' ,engage the trip after theshock reaches the ground, so that the'drum 21 will cooperate with theflexible chain 27 to rot-ate'the shock former through a small angleafterthe bot tom has dropped, this rotation beingsufiicient to allow theshock to fallandthe bot tom to pass from thereunder. When the. brace4L5- engages the trip 53, the end'55 will move the lever 23 in adirection todisengage the clutch from the drum 21 and traction wheel.When this takes place, the I I I mechanisni for'tr pping -thebottom ofthe tension will be released in the cha'in'27, and theshock former willbe leftstanding ,prac-- ti'call'y in a vertical position withrespect to"the frainel Inorder to insure a quiclzre turn, there is provided aresilient means As the shock former-nears the end ofits travel, thebrace 45 willengage the spring 56 and distort the same suiliciently' sothat when the chain 27 is slacked, the said spring 56 will st-art theturninovement, the bottom 43 is in its lower position, and in order toraise the 'sameto' the position shown-in Fig. 2, thereis 'provided aflexible chain 57, which passesover a pulle ts mounted on the lower ring14,

of the bottom as. This flexible member 57' downwardly parallel to thetine rod 35, and

shock former reaches its lowermost posiwhich is connected-to the tines38. A furprongs oi the bottom; When the bottom is is drawn'over a pulley58 mounted in the cross bar 30, a-ndfrom; there is led over'a secondpulley 59, mounted upon the bracket 36. From the pulley 59, the chain57passes O is. secured to one, ofthe tines; 38. As the 7 shock formerdescends, the first operation is to tighten-the chain 57 which resultsin a compression of the spring 39. Before-the tion as shown in Fig. l,the spring is compresseduntil the rigid collar'tO engages the bracket36, which prevents all further movement of that end of the flexiblechain57;

8O ther descent of the shock formerwill cause the flexible chain 57 todraw upwardlylupon the bottom 43, inasmuch as both the tine rod and thepulley 58 are moving away from the pulley 58. When the bottom 43'respect to the lower ring 14:, the projecting end 60 of the bottomengages a lug 61 rigid with the ring 14, the lug, 61 beingupon theopposite side of thepivot point of the bottom from the point where thechain 57 con-, nectsi to the bottom. Byreason ofthis lug 61, a further,descent of the shockformer will force the bottom up to a position'shownin Fig.*2, until the levers 47 engage the 5 locatedas just described,and the collar 40 engages the bracket 3.6,the chain 57 will be rigid andwill support the shock former 15 in its lower'position. As theshoclr'former assumes the position just described, the pin or trip rod18 will trip the pawl 9 to permit the accumulatedsheaves held by'thearms' 8, to be passed over the gate'lG into the shock-former Thisreturns ,the'shocki 6 formingreceptacle toits normal horizontal positionwith the door 16 open, and the shoclreris againin a position to gothrough the operation justdescribed.

Fi 4: of thedrawings: shows in detail the shocker. zThetrip-or trigger50 is provided with a longitudinalslot 63 within which 'worlrs the'boltor" other oivot member 51 f ing adaptedto engage the trigger 50, where-'129 as the otherend is bent downwardly and inwardly as at 65, to providemeans for en-i gr one of the prongs 49"ofthe bottom 43, iirS thebottomturns in a vertical plane,

thebody portion of the trigger 50, will 5 swing the dog l7 so thattheinwardlybent portion" 65 will release the prongs a9. One

of these devices is'arrangedupon either-side of the shock-former asindicated in Fig. 3.

InFig. 5'is shown a modified means for 1 0 wheel.

actuating the tines and tine rod. Instead of the spring 39, there isprovided a weight 62 which is rigid with the tine rod 35,the weight 62being connected to the chain or other flexible connection 57. Thisweight is so placed upon the tine rod 35, that its upper surface engagesthe'bracket 36to limit the upward movement of the tine 'rod 35 in a waysimilar to the action ofthe collar 40. When the shock former is turnedto vertical position, the weight 62 will be sufiicient to force thetines into the topsof-the sheaves and in this capacity act the same asthe spring 39. If the collar 40 be not used in the preferred form, itwill be seen of course that the spring 39 will be compressed to itsminimum length when the adjacent coils will touch each' other, in whichevent the supporting strain transferredby the chain 57, will be taken upby the spring 39. lVhichever form be used, however, it isdesirabletohave the driving means for forcing the tines downwardly andthe limiting means for determining the upward movement of the tinerod'35, made substantially in one piece. a y l In the rising of theshockformer, it is desirable that the brace 45. engage the spring 56before engaging the trip 53, and after the brace'45 has engaged the trip53,

it is desirable to have the trigger engage the dog47 for releasingthebottom. The reason for this is that itis desirable to storesufficient energy in the spring 56 before the clutch mechanism is thrownout of gear with the traction wheel to return the shock former past thecenter, and further it is desirable during the instant that the formedshock is falling, to have the shock former in stationary position, hencethe necessity for disengaging Having thus described the invention, whatis claimed as new is:
